Block 1, of mass m₁ = 1.30 kg , moves along a frictionless air track with speed v₁ = 29.0 m/s. It collides with block 2, of mass m₂ = 39.0 kg, which was initially at rest. The blocks stick together after the collision.
A: Find the magnitude π of the total initial momentum of the two-block system. Express your answer numerically.
B: Find , the magnitude of the final velocity of the two-block system. Express your answer numerically.
C: what is the change initial in the two block systems kinetic energy due to the collision ? Express your answer numerically in joules.

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
